ATH @ BOS
Home plate: Tom Hanahan
“The kind of night where the umpire is the least of the story.”
What this shows — how Tom Hanahan called the 142 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 132 right. Below, only his misses are plotted, alongside every pitch the ABS (Automated Ball-Strike System) reviewed on a challenge.
The zone, as he called it
The calls that moved the game
- 1+0.13▼8 · 1-0 strike called ball
Eli White vs Seth Johnson - 2-0.10▼4 · 0-1 ball called strike
Eli White vs Gage Jump - 3+0.10▲6 · 0-1 strike called ball
Jacob Wilson vs Justin Slaten
Run impact from the count run-value table: a missed strike three is worth far more than one on 3-0.
ABS — the Automated Ball-Strike System
4 pitches went to the robots · 1 overturned (ump overruled) · 3 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Willson Contreras — ump said strike, robot ruled strike: upheld.
- 2Tyler Soderstrom — ump said strike, robot ruled strike: upheld.
- 3Brian Serven — ump said ball, robot ruled ball: upheld.
- 4Jahmai Jones — ump said strike, robot ruled ball: overturned.
Our tracked-rulebook zone matched the ABS ruling on 3 of 4 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
